vMOTOR SUPPORT 0B, SUSPENSION.

Application med July' e,

struction' and combinations and arrangements lof parts which will. be described in this specification and set forth in the appended claims.

In the accompanying sheet of drawings, showing one embodimentof the invention which operates very effectively, Fig, 1 is a top plan view showing a'. portion of the chassis frame and showing conventionally the motorv 2o supported on the frame in accordance with my improved suspension, both the front and l rear endsvof the motor having, .in this instance, the improved insulating or isolating support; Fig. 2 is a sectional view on an enlarged scale substantially along the line 2-2 of Fig. 1; and Fig'. 3 is a view on a similar scale partly in elevation and partly in section looking in the direction indicated by the arrow in Fig. 2, the part in section being substantially along the line 3-3.

Referring now to the drawing, 10 represents the chassis frame and 11 the motor which is provided at its' forward and rear ends with supporting arms 12, which aregenerally rigidly and directly secured to the chassis frame. My improved motor 'supporting means may be applied to one end of the motor only such as therear end, or both to its forward' and rear ends and in Fig. 1, it is so shown but it is to be understood that the invention may be employed for the rear endor, in fact, to either end of the motor only if desired.

In accordance withm invention, thel mo tor arms 12 either at the ont, rear, or at both the front and rear ends of the motor, are connected to the chassis framein the following manner: A sheet steel sup-'porting plate-13 is attached by riveting or bolting tothe inside of the frame side channel, this member hav ing the equivalent of flanges 13a which engage the lflanges of the -frame side channel and, additionally, it has between the lianges 13a two portions 13b and 13 which are on the inside of the'frame channel, the portion 13b 1926. serial N0;`12o ,615.

being incl-ined vdownwardly and` inwardly away from the frame channel and the portion 13c downwardly and outwardly toward the frame channel. lThesetwo portions 13b and 13c are, in this instance, at right angles to each other but I do not regard that as a necessary'relationship, the important feature -being that the portion 13b to which the motor arm is attached is obliquely disposed with respectto the horizontal and vertical.

Two of these supporting members 13' Iare disposed on the opposite sides of the chassis frame -preferably opposite the rear motor varms 12 and, in this instance, two are arranged opposite thefront motor arms. The two rear plates are, in this instance, longer than the front plates for a purpose to bedescribed.

1 The motor is supported between these angularly disposed members,there being interposed between the motor 4arms and thas in,A

clined portionslb of the plates, resilientbrv insulating pads 14 such as rubber, fibre, Wood,

etc. but preferably the former. This serves to isolate or insulate the motor from the chassis frame so as to prevent the transmisysion of mechanical vibration and noisesv from the motor to the chassis frame. as the motor must now be securely attached v'tothe chassis frame and the attachments must Inasmuch not form any direct mechanical contact be- 4 tween the motor and chassis frame, a-second insulating pad 15 of similar material is placed on the outer side of the inclined portion 13" of the supporting member 13 andthe parts areheld in'place by a steel plate 16 at the outerside of this padvand by attaching the i bolts 17 extendingA throughl alll these parts,

including ears on the motor supporting arm.

It is important that the attaching boltsvclear' the plate 13 so as to avoid mechanical-con- 'tact between these parts, as shown 1n Fig. 3.

Inasmuch as the ordinary method of vsuspending the motor rigidly yby attachin the iy rear motor arms to the chassis frame irect Nconstitutes a very'rigid vtie up 'which stiens theframe and protects the body of the car against stresses set up by the weaving of the frame, it is essential that the rigidity formerly secured by the rigid attachment of the rear motor arms to' the 4frame be maintained or secured in some other manner. This result is accomplished in this case by the use'of a rigid. cross connecting member closev t o' the rear motor arms, this member, in this -instance, including a tubular cross piece 1S fastened by brazing, welding or otherwisev I into castings 19, bolted to the lower inclined faces 13c of the supporting plates. By thus rigidly connecting together the two oppositev supporting plates 13 to which the rear motor arms are yieldingly attached, the necessary rigidity isobtained at this point.

The chassis frame generally has a front cross member-a which is suiciently close to theifront-end of the motor to avoid the necessity of a special cross bracingmember inf the event my improved insulating supporting means is employed for the front end "5 ybf the motor.

It will be observed that by the oblique or inclined arrangement of the yieldable insulating members, both horizontal and vertical stresses can be very eii'ectively resisted, and, accordingly, not only is the-motor isolated or insulated from the chassis frame but the arrangement of the supporting parts is such -that stresses in any directionare successfully withstoodand consequently, the motor suskpesion is very durable. y

do not desire to be confined to the predetails but aim in my claims to cover downs for said motor abutments.

2.The combination' with a chassis frame and motor, of a motor suspension comprising a supporting member on each side thereof disposed diagonally with respect to the horizontal and vertical, yieldable means between said members and the motor, and holddowns for said motor yieldably mounted with respect to the supporting members and rigidly connected with said motor.

3. A chassis comprlsmg a chassis frame, al

motor, plates secured to the side members of the chassis frame -with supporting faces inclined to the horizontal and vertical and arranged on opposite sides of the motor, yieldable pads between said faces and the motor,

' terial on opposite si and ustable means for clamping down said motor on said pads. s

4..A chassis comprising a chassis 'frame and a motor, the frame being provided on opposite sides of the motor with motor supportingplates having (faces inclined downwardly and inwardy,

es of said plates, a motor arm above the upper pad, a rigidplate below the lower pad, and

said arm and rigid plate together and out of metal contact with said motor support-l ing plate.

5. A motor support for a chassis comprising a supporting member having downwardly and inwardly inclined upper and lower faces, a motor arm on one side of the member,' a rigid plate on the other, yieldable pads on o posite sides of the supporti'n member, and olts for clamping said arm an plate together and out of Acontact with the supporting member. y l

6. In a chassis, a chassis frame, a motor having oppositely disposed supporting arms, a pair of supporting plates securedto the chassis frame, the arms heilig yieldingly secured to these platesand a rigid member extending crosswise of the chassis frame allid having its opposite ends secured `to said p ates.

7. A chassis having a frame and a motor, a pair of motor supporting plates secured to the inner sides of the opposite channels of the frame and havin inclined faces secured to opposite sides of t e motor with yieldable means between the motor and said faces, and a rigid member extendino' crosswi e of the frame, adjacent the yieldzable support thus provided.

8. A chassis comprising a frame and a motor, a pair ofA motor supportin cured to the inner sides of the si means for clamping' plates se-. e members liu i pads of yieldable maf of the frame and having faces disposed downwardly and inwardly and faces disposedidownwardly and outwardly, the motor aving arms yieldingly connected to the firstnamed faces of the plates and a rigid bracing ,member extending crosswise of the frame an attached to the second-named faces of the plates. v

In testimony whereof, I hereunto aix my signature.
